Hello everyone & Happy New Year!! I haven’t posted before, but I’m on here a lot reading posts to educate myself on treatments.
My Mom was diagnosed Feb 2023 de novo stage 4 breast cancer to bones only. She had 2 1/2 rounds of Ibrance from April 23- June 23 (stopped Ibrance in July 23 due to shortness of breath). Onc has kept her on Letrozol only now. Her lastest PET scan a few days ago shows all tumors are still getting smaller. There is no new progression. I don’t understand how the tumors can still shrink when she is not on Ibrance and only Letrozole. Does the Ibrance stay in the system and keeps working? Or can Letrozole alone shrink the tumors? We haven’t had her Onc appt yet to go over the scan. But I’m wondering if Letrozole alone can shrink away the tumors. I understood that the treatments would only hold back the progression. Well I guess I shouldn’t say shrink away, the tumors are still there.
Thanks in advance for any input. I appreciate this forum and all of you for sharing information!!!
